Maintenance and care
pressure warning light will go off and
the inflation pressure of each tire will be
displayed on the multi-information dis-
play.
Even if the vehicle is not driven at
approximately 40 km/h (25 mph) or
more, registration can be completed by
driving for a long time. However, if reg-
istration does not complete after driving
for 1 hour or more, perform the proce-
dure again from the beginning.
7Initialize the tire pressure warn-
ing system. (P.468)
QWhen registering ID codes
OID code registration is performed
while driving at a vehicle speed of
approximately 40 km/h (25 mph) or
more.
OBefore performing ID code registra-
tion, make sure that no wheels with
tire pressure warning valve and trans-
mitters installed are near the vehicle.
OMake sure to initialize the tire pres-
sure warning system after registering
the ID codes. If the system is initial-
ized before registering the ID codes,
the initialized values will be invalid.
OID codes can be registered by your-
self, but depending on the driving con-
ditions and driving environment,
registration may take some time to
complete.
OAs the tires will be warm when regis-
tration is completed, make sure to
allow the tires to cool before perform-
ing initialization.
QCanceling ID code registration
OTo cancel ID code registration after it
has been started, select “Identifying
Each Wheel & Position” on the multi-
information display and press and
hold again.
OIf ID code registration has been can-
celed, the tire pressure warning light
will blink for approximately 1 minute
when the power switch is turned to ON and then illuminate. The tire pres-
sure warning system will be opera-
tional when the tire pressure warning
light turns off.
OIf the warning light does not turn off
even after several minutes have
elapsed, ID code registration may not
have been canceled correctly. To can-
cel registration, perform the ID code
registration start procedure again and
then turn the power switch off before
driving.
QIf ID codes are not registered prop-
erly
OIn the following situations, ID code
registration may take longer than
usual to be completed or may not be
possible. Normally, registration com-
pletes within approximately 30 min-
utes.
If ID code registration is not complete
after driving for approximately 30 min-
utes, continue driving for a while.
• Vehicle is not parked for approxi-
mately 20 minutes or more before
driving
• Vehicle is not driven at approximately
40 km/h (25 mph) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles
and system cannot recognize tire
pressure warning valve and transmit-
ters of your vehicle over those of other
vehicles
• Wheel with tire pressure warning
valve and transmitter installed is
inside or near the vehicle
If registration does not complete after
driving for 1 hour or more, perform the
ID code registration procedure again
from the beginning.
OIf the vehicle is reversed during regis-
tration, the data up to that point is
reset, so perform the registration pro-
cedure again from the beginning.
OIn the following situations, ID code
registration will not be started or was
not completed properly and the sys-
tem will not operate properly. Perform

4727-3. Do-it-yourself maintenance
the ID code registration procedure
again.
• If, when attempting to start ID code
registration, the tire pressure warning
light does not blink slowly 3 times.
• If, when the vehicle has been driven
for about 10 minutes after performing
ID code registration, the tire pressure
warning light blinks for approximately
1 minute and then illuminates.
OIf ID code registration cannot be com-
pleted after performing the above pro-
cedure, contact any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
QEffects of incorrect tire inflation
pressure
Driving with incorrect tire inflation pres-
sure may result in the following:
OReduced fuel economy
OReduced driving comfort and poor
handling
OReduced tire life due to wear
OReduced safety
ODamage to the drive train
If a tire needs frequent inflating, have it
checked by any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer.
QInstructions for checking tire infla-
tion pressure
When checking tire inflation pressure,
observe the following:
OCheck only when the tires are cold.
If your vehicle has been parked for at
least 3 hours or has not been driven
for more than 1.5 km or 1 mile, you
will get an accurate cold tire inflation
pressure reading.
OAlways use a tire pressure gauge.
It is difficult to judge if a tire is properly
inflated based only on its appearance.
OIt is normal for the tire inflation pres-
sure to be higher after driving as heat
is generated in the tire. Do not reduce
tire inflation pressure after driving.
OPassengers and luggage weight
Tire inflation pressure
Make sure to maintain the
proper tire inflation pressure.
Tire inflation pressure should
be checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks. (P.564)

Maintenance and care
should be placed so that the vehicle is
balanced.
When replacing wheels, care
should be taken to ensure that they
are equivalent to those removed in
load capacity, diameter, rim width
and inset*.
Replacement wheels are available
at any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
*: Conventionally referred to as offset.
Toyota does not recommend using
the following:
 Wheels of different sizes or types
 Used wheels
 Bent wheels that have been
straightened
QWhen replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire
inflation pressure. Whenever wheels are replaced, tire pressure warning valves and transmitters must be installed.
( P.465, 474)
WARNING
QProper inflation is critical to save tire performance
Keep your tires properly inflated. If the tires are not properly inflated, the following conditions may occur
which could lead to an accident resulting in death or serious injury:
OExcessive wear
OUneven wear
OPoor handling
OPossibility of blowouts resulting
from overheated tires
OAir leaking from between tire and
wheel
OWheel deformation and/or tire dam-
age
OGreater possibility of tire damage
while driving (due to road hazards, expansion joints, sharp edges in the road, etc.)
NOTICE
QWhen inspecting and adjusting
tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and cause an air leak, resulting in
decreased tire inflation pressure.
Wheels
If a wheel is bent, cracked or
heavily corroded, it should be
replaced. Otherwise, the tire
may separate from the wheel
or cause a loss of handling
control.
Wheel selection

4747-3. Do-it-yourself maintenance
Use only Toyota wheel nuts and
wrenches designed for use with
your aluminum wheels.
 When rotating, repairing or
changing your tires, check that
the wheel nuts are still tight after
driving 1600 km (1000 miles).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine bal-
ance weights or equivalent and a
plastic or rubber hammer when
balancing your wheels.
WARNING
QWhen replacing wheels
ODo not use wheels that are a differ-
ent size from those recommended in the Owner’s Manual, as this may result in a loss of handling control.

tubeless tire. Doing so may result in an accident, causing death or seri-ous injury.
QWhen installing the wheel nuts
Never use oil or grease on the wheel
bolts or wheel nuts. Oil and grease may cause the wheel nuts to be excessively tightened, leading to bolt
or disc wheel damage. In addition, the oil or grease can cause the wheel nuts to loosen and the wheel may fall
off, causing an accident and resulting in death or serious injury. Remove any oil or grease from the wheel bolts
or wheel nuts.
QUse of defective wheels prohib-
ited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an accident.
NOTICE
QReplacing tire pressure warning valves and transmitters
OBecause tire repair or replacement may affect the tire pressure warning valves and transmitters, make sure
to have tires serviced by any autho- rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer or other qualified service shop. In addition, make sure to pur-chase your tire pressure warning
valves and transmitters at any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
OEnsure that only genuine Toyota
wheels are used on your vehicle. Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.
